nanocrystalline magnesium oxides were prepared by sol–gel method and were characterized by x-ray diffraction, n2-bet, sem and infrared spectroscopy techniques. the results confirmed the formation of nano- mgo materials with crystallite size in range of 5-20 nm and surface areas of 336-556m2/g. the product has been tested as destructive adsorbent for the decontamination of (2-chloroethyl) ethyl ...

2-Chloroethyl ethyl sulfide (CEES) is a simulant for the chemical warfare agent, bis(2-chloroethyl) sulfide, also known as mustard gas. Functionalized Zr-BTC synthesized and exploited optical detection of CEES.

An air pollution modeling study was conducted to investigate the odorous effects of volatile organic compounds (VOCs) emissions from a sanitary landfill area on ambient air quality. The atmospheric dispersion of hydrogen sulfide (H(2)S) and 22 VOCs was modeled. Industrial Source Complex v3 Short Term (ISCST3) model was used to estimate hourly concentrations of odorous VOCs over the nearest resi...

A case histories course was introduced into the CEE curriculum at University of Louisville in fall 2004, to address various specialties and to synthesize what the students from various specializations learned in different courses. The course, patterned after a course taught by Dr. Ralph B. Peck at the University of Illinois, satisfies many ABET course outcomes and educational objectives. By inv...

Polyols can be synthesized from carbohydrates in bioor chemo-catalytic way. The conversion of polyols with two hydroxyl groups in 1,4-positions, for example 1,4-butanediol, results in furan derivatives. In contrast, during the dehydration of diols with two vicinal hydroxyl groups, for example, 1,2-propaneand 1,2-butanediol, aldehydes or ketones are formed [1] . This will be presented exemplaril...

The influence of ß-dihydroxyl groups in the alkaline hydrolysis of glucosidic bonds is examined. In deriva­ tives of ß-D-glucopyranosides, all hydroxyl groups are trans to each other, and the alkaline elimination of sub­ stituted methyl ethers in positions C-2 and C-4 can be explained, in part, by assistance from neighboring trans a-hydroxyls. The rate of degradation of ethyl 2-2-methyl-ß-D-glu...
